1. Features
The Digital Retinal Camera CX-1 is used to observe the retinas of patients’ eyes and take photographs of
them. The camera has the following features.
Both mydriatic and non-mydriatic modes in a single unit
The CX-1 includes a mydriatic mode and non-mydriatic mode, and each mode can be selected with a
single switch.
In the mydriatic mode, the optical viewfinder is used for observation. In the non-mydriatic mode, the
observation monitor on the special digital camera is used for observation.
Fundus autofluorescence photography
Fundus autofluorescence photography is possible in both mydriatic and non-mydriatic modes.
Special digital camera
The CX-1 includes a special digital camera using EOS digital technology as a standard accessory.
This enables the CX-1 to fully maximize Canon technology for shooting high-quality, high-resolution
diagnostic images.
Compact, user-friendly design
Panning and tilting functions are provided as standard options in a compact, lightweight design.
The compact body makes it easier to assist patients and provides significantly improved ease-of-operation.
Vertical movement of the main body by a motorized chin rest and an operation lever significantly improves
alignment operability.
Small pupil photography function
The CX-1 can photograph dilated pupils with a diameter of at least 5.1 mm in the mydriatic mode, with
50° of their field angle. It can photograph non-dilated pupils with the diameter of at least 4.3 mm in the
non-mydriatic mode, with 45° of their field angle.
The CX-1 provides the small pupil photography function for patients whose eyes are difficult to dilate.
Using the function, it can take photographs dilated pupils with a diameter of at least 4.3 mm and nondilated pupils with a diameter of at least 3.8 mm.
System optimized for digital photography
With the Retinal imaging control software (called “control software” below), images photographed by the
CX-1 can be browsed, processed, stored, output to the DICOM storage server, exported to DICOM files,
and output to a printer.
The settings for the lighting system filter, flash intensity, and digital camera are automatically optimized
for each photography mode – color, red-free, cobalt, fluorescein angiography, or fundus autofluorescence.

Guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the CX-1, including cables,
than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
d = 1.2 P
d = 1.2 P 80 MHz to 800 MHz
d = 2.3 P 800 MHz to 2.5 GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter
manufacturer and d is the recommended
separation distance in metres (m).
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site surveya, should be
less than the compliance level in each
frequency rangeb.
Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflections from structures, object and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. For assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the CX-1 is used exceeds
the applicable RF compliance level above, the CX-1 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary,
such as reorienting or relocating the CX-1.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
